Button



Nov. 13, 1934. -A. A. CAVICCHI BUTTON Filed Oct. 6, 1932 Patented Nov. 13, 1934 UNITED STATES PATENT OFFICE 8 Claims.

My invention relates to buttons wherein the front and back are made from a continuous piece of material,-also to the eye and means for attaching it to the button.

The objects of the invention are as follows:

To construct buttons by a continuous series of operations to their completion, thus doing away with handling of the parts between operations, as is the case when the back and front are made of separate parts and require assembling and secur'-' ing together by separate operations.

A further object of my invention, is to secure the eye in the button so it will not rotate therein and to form an eye so it may be attached to and detached from a thread, cord or other means, yet will not be accidently detached in use.

In the drawing accompanying this specification and forming a part thereof: Fig. 1 is a plan of a blank from which the body of the button is made; Fig. 2 is an edge viewof same; Fig. 3 is a plan view of the blank after the front portion is cupped, the eye hole punched and the parallel projections formed; Fig. 4 is a sectional edgeview through line 4-4 Fig. 3; Fig. 5 is a sectional elevation of a completed button taken through its center, showing a side view of the eye portion. Fig. 6 is a sectional elevation'taken at right angle to the view shown in Fig. 5 to show the manner in which the free end of the eye is offset to permit insertion of the fastening means.

Fig. 'l is a top view of the head of the eye and Fig. 8 is a side view of an eye.

Fig. 9 is a side view of a modified form of eye made of wire and Fig. 10 is a plan view of the bottom of the back of a button with the eye shown in Fig. 9 in place.

A blank 12 is punched out and formed so the part 13 is slightly larger than the part 14. The two being connected by the portion 15, a projecting lug 16 is formed on the part 13. The next operation cups the portion 13 as shown in Figs. 3 and 4, punches the eye hole 17, and strikes up the projections 1818. At the next operation the shank 19 is inserted and the parts 13 and 14 are folded upon each other at the line 2020 and assume the relative positions shown in Figs. 5 and 8, thereafter the portion 16 is folded under and upon the portion 14 as shown in Fig. 5 to firmly hold the parts in their finished condition ready for use.

Fig. '1 shows the preferred form-of shank. This consists of the head portion 19, having oppositely disposed flattened portions 2222 of a width between them to permit the head to be inserted between the projections 18-18. By this construction, the head 19 is prevented from turning around after the parts are assembled.

The head 19 is provided with the circular eye portion 23, bent slightly spiraling so the end 24 stands away from the body of the eye. This permits insertion of the fastening means, such as the loop of a cord, thread, wire or other means.

A modified form of eye may be made from wire as shown in Fig. 9. Instead of a head being formed on the shank, the end 25 has a return bend, the two portions standing in a plane at right angles to the shank, the eye portion 28 having a spiraling eye same as shown in Fig. 8.

Buttons embodying my invention are made by continuous automatic Y operations without any handling of theseparate parts between the operations. The method or process used, consists of a series of power operated tools which comprises blanking tools to produce the blank shown in Fig. 1. The next step is to form the portion 13 as shown, punch the hole 17 and form the indents 1818. Next the portion 14 is folded to cover the concave opening of the portion 13.

Previous to this operation the shank is passed through the hole 1'7, and its end bent 'toform the eye 23. After the portion 14 is folded upon the portion 13, the lug 16 is foldedover the back of the portion 14 as shown in Fig. 5, which completes the cycle of operations.

Buttons can be produced by this process or method at much less cost than by making the backs and fronts of buttons separately and thereafter assembling and securing them together.

Having described my invention what I claim is:

upon the concave face of the front portion and secured in such position by a lug.

2. A hollow button having a front and back portion folded upon each other and secured together to form a cup-shaped recess, a hole in the back portion, a shank portion having a head enclosed in the recess and extending through the hole in the back and a spiraling eye formed. from the projecting end of the shank to permit the loop of a thread to be attached and detached therefrom.

3. A hollow button, a cup-shaped front portion, and a flat back portion joined thereto, a lug to secure the back portion in position against the concave face of the front portion and a shank secured in the back portion having a spiraling eyeadapted to permit a looped member to be attached to and detached therefrom.

4. A button having a wire shank fixedly attached thereto, the free end of the wire shank being bent to form a normally open eye formed to permit the loop of a thread to be engaged therewith.

5. A button having a wire shank attached thereto, a constantly open eye formed in the free. end of the shank and shaped to permit the loop of a thread to be attached thereto and means to prevent the shank turning around in the button.

6. A button having a wire shank having one end portionbent spirally to form a normally open 1,980,909 v eye adapted to receive an attaching loop, the

opposite end of the shank constituting a head non-rotatably secured to the back of the button.

7. A button having a wire shank fixedly attached thereto, the free end of the wire shank being bent to form a constantly open spiral eye formed to permit the loop of a thread to be engaged therewith.

8. A button having. a wire shank attached thereto, a constantly open spiral eye formed in the free end of the shank and shaped to permit the loop of a thread to be attached thereto, and means to prevent the shank from turning around in the button.
